2.3 Inter-domain data transfer system architecture: From raw patient data to case template.
At the Medical University Vienna (MUW) a system for the generation of study cases from data routinely
documented at the Vienna General Hospital (AKH) has been established. A simplified view of the system
architecture is shown in Figure 2. After the selection of a patient in the General Hospital’s i.s.h. med-based Hospital
Information System (AKIM), a study case document can be created. Data from clinical documents, laboratory
results, diagnoses etc. are included according to a predefined case profile. The anonymization of the clinical content
is realized through an automatic procedure, which replaces e.g. patient name and dates, and completed by the
responsible physician.
Over a HL7 CDA (Goosen & Langford, 2014) interface the case data is exported into the MUW intranet. The
onward transfer is conducted by the Science & Research platforms of the MUW. Its centerpiece is the RDA
(Research Documentation & Analysis) platform, which is an IT system for the integrated support of medical
research. The platform provides scientifically relevant data from the AKIM routine documentation in highly
structured form in a central database. The image data function of the platform offers a range of support for
multimedia content, which can also be integrated in the created study case templates. A clinical trial management
system, a bioinformatics platform and an experts system complement the services provided for the support o
